4-level Enchantment (ritual)
Upon wielding a weapon you are proficient with you can sacrifice HP equal to dice type of your choice and that weapon becomes magical if its not already and does damage of the die you sacrificed. The weapon takes a shape of your choosing and a non-bladed weapon appears to be bladed. This weapon will retain this enchantment even if it leaves your hand.
At higher levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1 of the dice you choose (both you and the weapon) for every slot level above 4th.
